Inventov-= ZZOI 'n y I JAMES COWLEY l t ND ROBERT C. DILS, OF ST. LOUIS, .MISSOURI.

To all whom it may concern:

Be it known that we, JAMES COWLEY and ROBERT C.- DILs, citizens of the United States, residing at the city of St. Louis,- in

the State of Missouri, have invented certain new and useful Improvements in Auxiliary,- Power Devices, of which the following is a specification. I

This invention relates to internal combustion engine s,'and has for its object the utilization of the escape of the products of-- combustion through the exhaustffor the purpose of increasing the power ofthe englne This is accomplished by mounting a turbine (preferably of the direct impulsetype) upon or in connection with the main drive-shaft and by locating the said turbine in the path of travel of the said gases between-the exhaust pipe and the exhaust-outlet or in the saidexhaust pipe.- 1

In the accompanying drawings, forming part of this specification, in which like num .bers of reference denote like parts wherever they occur, I Y I Figure 1 is a sectional view 'onthe line l.1 in Fig. 2; and

Fig. 2 is a sectional view on the line 2-2 in Fig. 1.

Upon the main drive-shaft 1 of the englne (or any other shaft to be driven) is mounted a rotary member 2, which is preferably keyed 'or splined thereto, as at 3.

The said rotary member 2 is provided with wings 4, which project outwardly therefrom and into haust pipe 5 and exhaust outlet 6, or between two parts of the said exhaust pipe.

A housing 17 incloses the said member 2 and its wings, 4, -a cap 8 being. attached thereto by screw-studs 9. Shaft 1 loosely revolves within sleeves 10 and 11, the bosses Y12 and 13 of which, respectively, closely engage the sides'of member 2. i

The housing 7 is attached to exhaustpi e 5 ?by bolts 14 and to exhaust outlet y bolts 15 in the .way shown in the drawings -or in any other suitable'manner. 1

1 Each wing 4.'is rovided with a bent portion 16,' in order t at the gases in exhausting will morefirmly' grip the said, wings.

Bail ie-plates 17 prevent the return of the said vgases and direct them,forward in the directiozrshown by the. arrow in Fig. 1,

thus pressing on wings or blades 4 and forcing the rotation of member 2 and with it shaft 1. As shaft 1 is otherwise propelled this gives an increase of power. There is barely clearance between bafileplates 17 and the bent parts 16 ofwings 4,

This is true as between the said parts 16 and the part 18 of'the housing 7, which I close fit at the point 18 sure upon the engine.

The gases are expelled with considerable force from the. cylinders'of the engine into pipe 5, and this force adapts'the same to propel the rotatable member. 2.,

Having thus described this invention, we

herebyreserve the benefit of all changes in form, arrangement, order, or use of parts,

as it is evident that man minor changes may be made therein without departing from the spirit of this invention or the scope of the following'claim.

.We claim:

In combination with an engine-exhaust outlet, an exhaust delivery element, a hous-- ing having an inlet and an outlet communiprevents back-pres cating with said exhaust delivery, said inlet and exhaust being located on the same wall of the-housing, a shaft having connection with the engine, a turbine in the housing and mounted on saidv shaft carrying radial peripherally disposed blades having their outer portions disposed rearwardly, the opposite sides of the housing having bearlng bosses on their inner sides for spacing the blades slightly from the adjacent portions of said housing sides,forwardly-dis-.

posed oblique blades carried on the rear wall of the housing starting at apoint-in proximity to the inlet and finishing at a point in proximity to said outlet and adapted for' cooperation with the blades of the turbine for insuring passage of the exhaust [gases in but one direction, the forward wall of the housing being arranged'rearwardly of the outlet and affording only sufiicient' clearance forthe blades on the turbine: to

allow free rotation of the-latter, whereby to prevent return of exhaust gases. and the resultant back pressure on the engine.

In. testimony whereof we hereunto afiix our signatures.
